x=6 seat boats y=8 seat boats {6x+8y=58 6x+8y= 58 <- { x+y=9 (multiply
by -6)--> -6x-6y=-54 <-(add the two equations) 2y= 4 x+(2)=9 y=
2 x=7 X=7,Y=2 (7 six seat boats, and 2 nine seat boats!)About me: I want to thank mmy big brother for showing me the new
stuff he learns in school like how to do this problem. He shows me all
the new things he learns and is now teaching me some sign language. I
really like school even though I didn't as good as a start as my brother
did. But I am still trying my hardest and I want to do good in school.

If all 9 boats have 6 seats we would fill only 54 people. If 2 boats out
of 9 have two more seats each we would fill all 58 peaople. So we need
7 boats with 6 seats and 2 with 8.About me: I am in 3rd grade and like math.

Q1: There are 2 8-seated boats
Q2: There are 7 6-seated boats
We got our answer by multiplying a handful of numbers. First we tried
8X5 and 6X3 but that was only 8 boats so we knew we were wrong.We were
really puzzled but we kept trying number after number until we got 8X2=
16 2+7=9 6X7=+42=58About me:

Q1: 7 boats with 6 seats
Q2: 2 boats with 8 seats
2x8=16 58-16=42 So this tells me that I need 2 boats with 8 seats and
7 boats with 6 seats. And so 7+2=9 so that would be 9 boats.About me: I'm a A student in 4th grade. I like math reading writing
